The wheel is one of the main components of the wheel and axle which is among the most six simple machines. Wheels, at the side of axles, allow heavy objects for being moved easily facilitating movement or transportation while supporting a large quanity, or performing labor in machines. Wheels are also for other purposes, perhaps a ship's wheel, wheel, potter's wheel and flywheel.Common examples are merely in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together currency axles. To ensure that wheels to rotate, a moment in time must be relevant to the wheel about its axis, either by gravity or by the effective use of another external force or torque.The English word wheel hails from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, a long-term form of the main *kwel- "to revolve, move around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, these both meaning "circle" or "wheel ".Precursors of wheels, identified as "tournettes" or "slow wheels", were known with the Middle East by 5th millennium BCE (one of the primary examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). These folks manufactured from stone or clay and secured to the floor along with a peg from the center, but required effort to turn.

The original proof wheeled vehicles appears on the better half of this 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), hence the question of which culture originally invented the wheeled vehicle 's still unsolved.The first well-dated depiction of your wheeled vehicle (here a wagon — four wheels, two axles) is along the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated inside a Funnelbeaker culture settlement in southern Poland.The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia (Ljubljana Marshes Wooden Wheel) is dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.2 types of early Neolithic European wheel and axle are known; a circumalpine style of wagon construction (the wheel and axle rotate together, like in Ljubljana Marshes Wheel), thinking that for the Baden culture in Hungary (axle fails to rotate). They both of them are dated to c. 3200–3000 BCE.In China, the wheel was certainly present aided by the adoption in the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
